Valve Electric Device
Model : ZB30-60/60AB
Scope Supply : Actuator only, NOT Include Valve
Brand : Changzhou Power Station
ZB series valve electric device is a two-position valve electric drive device, suitable for valves with valve discs in linear motion, such as stop valves, gate valves, throttle valves, diaphragm valves, etc. After being combined with a two-stage reduction device, it can also be used for valves with valve discs in rotary motion, such as ball valves, butterfly valves, etc. The product has passed the type test and ten thousand life test, and its performance indicators meet the requirements of JB/T8528-1997 standard.
The output torque ranges from 25N·m to 400N·m (divided into three machine base sizes), and the output speed is available in eight options: 12, 18, 24, 30, 36, 42, 48, and 60r/min. The manual speed ratio is 1:1. Two connection sizes are available: torque type and thrust type, which meet the standards of JB2920 and ISO5210 respectively. The travel controller can be expanded to four positions (open, close, middle 1, middle 2). The valve position transmitter (4~20mA current output) is available as an accessory.
